Merge tag 'sound-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "It was a busy development cycle at this time, as you can see a wide
  range of changes in diffstat.  There are no big changes but many
  refactoring and improvements.  Here we go some highlights:

  ALSA core:
   - Procfs codes were cleaned up to use seq_file
   - Procfs can be opt out via Kconfig (only for EXPERT)
   - Two types of jack API were unified finally; now both kctl and input
     jack devs are handled via a single function call.

  HD-audio:
   - Continued code restructuring for the future ASoC driver; now HDA
     controller driver is split to a core helper module.
   - Preliminary codes for Skylake audio support in HDA core.
   - Proper i915 gfx power well management for SKL & co
   - Enabled runtime PM as default for Intel HDMI/DP codecs
   - Newer Tegra chip supports
   - More quirks for Dell headsets, Alienware (with CA0132), etc.
   - A couple of DRM ELD helper API functions

  ASoC:
   - Support for loading ASoC topology maps from firmware, intended to
     be used to allow self-describing DSP firmware images to be built
     which can map controls added by the DSP to userspace without the
     kernel needing to know about individual DSP firmwares
   - Lots of refactoring to avoid direct access to snd_soc_codec where
     it's not needed supporting future refactoring
   - Big refactoring, cleanup and enhancement for the Wolfson ADSP
     driver
   - Cleanup series for TI TAS2552 and R-CAR drivers
   - Fixes and improvements on RT56xx codecs
   - Support for TI TAS571x power amplifiers
   - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs
   - Support for x86 systems with RT5650 and Qualcomm Storm
   - Support for Mediatek AFE (Audio Front End) unit
   - Other various small fixes to ASoC codec drivers

  Firewire:
   - Enhanced to allow non-blocking streams to use timestamp
     synchronization
   - Improve support for DM1500 and BeBoBv3

  Misc:
   - Cleanup of old pci API functions over all PCI sound drivers
   - Fix long-standing regression of the old powermac i2c setup"
